I have a problem with the following code ,it does not give the required random binary value for a number greater than 32 .Is there a way to get it to work for atleast 64 bit binary answer ;and to convert this binary back to decimal. The perl I use does not have `Q' 
use strict
  my($num2,$num1,$binary,$j );
print "enter the number\n";
$num2=rand 2**$j;
$num1=int $num2;
$binary = dec2bin($num1);
print "binary=$binary\n";
sub dec2bin
  {
    my $str =join '', unpack "B32", pack "N", shift;
    $str=substr($str,-$j);    
    return $str;
  }
